Embodiment 1

[0012] Embodiment 1: After passing each raw material through a 100-mesh standard sieve, get 20 parts of moisture-proof ammonium perchlorate, 35 parts of single- and double-base powders, 5 parts of aluminum-magnesium alloy powder, and 20 parts of nitroguanidine according to the ratio in parts by weight. Mix the components evenly by several times of rapid sieving, and add 20 parts of acetone solvent for every 100 parts of the mixed drug to adjust the humidity according to the ratio of parts by weight. into various specifications of granules, and dried. The preparation of the propellant with micro-smoke for fireworks is completed.

Embodiment 2

[0013] Embodiment 2: The difference from Example 1 is that the composition and the weight-number ratio of the micro-smoke propellant for the fireworks are: 30 parts of moisture-proof ammonium perchlorate, 52 parts of single- and double-base powders, titanium hydride powder 5 parts, 5 parts of hemp stalk charcoal powder, 12 parts of aminoguanidine nitrate. Use ethyl acetate solvent to adjust humidity and granulate.

Embodiment 3

[0014] Embodiment 3: The difference from Example 1 is that the composition and the weight-number ratio of the micro-smoke propellant for the fireworks are: 10 parts of moisture-proof ammonium perchlorate, 70 parts of single- and double-base powders, 10 parts of aluminum powder parts, 5 parts of nitroguanidine. Use ethanol to adjust humidity and granulate.

Abstract

The invention discloses a micro smoke gun propellant for fireworks, which comprises the following components in part by weight: 30-70 parts of nitrocotton, 5-30 parts of moistureproof ammonium perchlorate, 2-10 parts of reducing agent and 5-20 parts of high-nitrogen substance. The safety performance indexes of the micro smoke gun propellant for fireworks completely meet the requirements of the national standard. The micro smoke gun propellant for fireworks not only can meet the propelling requirement of the product, but also produces micro smoke when the gun propellant is combusted. According to the light transmittance detection result, the smoke quantity produced by the gun propellant is only about 30% of that of the traditional equivalent corresponding products.

Description

technical field [0001] The invention relates to a pyrotechnic agent for fireworks, in particular to a small-smoke propellant for fireworks. Background technique [0002] In the prior art, the propellant powder for fireworks all uses black powder or other similar black powder configured with potassium nitrate, charcoal and sulfur. The smog produced by the burning of black powder is too large, and together with the smog produced by other discharge products, the effect of large-scale fireworks shows that are set off is seriously affected, and it also causes great pollution to the urban air near the discharge site. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current black powder propellant has too much smoke when it burns, and to provide a kind of smoke propellant for firework that not only has only a little smoke after burning, but also can maintain the firing force, ignitability and stability of the black powder....
